maentoz Patented Oct. 4, 1932 UNITED STATES PATENT SEALING STRIP GQNSIRIUQTIQN Application filed July 23, I928. Serial; No. 294,885.

This application is a continuation in part of my copending Patent No. 1,824,212 of September 22, 1931. The object of the invention, as in the patent, is to provide a seal '5f ing device which operates automatically when a slidable closure member is moved to its closed position. The particular closure member described and illustrated herein is a sliding window sash.

Another object of the invention is to provide a sealing device which automatically comes into operation when the sashes are moved to closed position, in order to prevent rattling of the sashes and loss of heat through the window.

The invention includes, in conjunction with the sashes, sealing strips pivotally attached to the frame. Springs acting on these strips tend to project one end thereof into the path of the sashes. When the latter are moved to closed position, they engage the projected ends and turn the strips on their pivots so that they come into longitudinal engagement with the sashes.

The invention is fully disclosed in the fol-' lowing description and in the accompanying drawing in which Figure 1 is a fragmentary front elevation of a window equipped according to the invention;

Fig. 2 is a vertical section thereof showing the sashes in closed position;

Fig. 3 is a vertical section showing the sashes in open position; and

Fig. 4 is a detailed section on the line 44 of Fig. 2.

Reference to these views will now be made by use of like characters which are employed to designate corresponding parts throughout.

In the several figures is illustrated a window of the conventional sliding sash or clouble-hung type comprising a frame 1 in which a lower sash 2 and upper sash 3 are slidably mounted and guided by parting strips 4.

In the lower part of the frame is mounted a pair of sealing strips 5 each turning on a pivot pin 6 passed through the lower portion thereof and into the adjacent j amb. At the upper part of each strip is a short transverse slot 7 through which passes a pin 8 entering the jamb. The upper or free ends of the strips are joined each by an expanded spring 9 to the adjacent jamb, whereby the lower ends 10 of the strips are projected into the path of the sash 2. In like manner the pair of sealing strips 11 are hung in theupper part of the window frame on the projected pins 12 entering the adjacent jamb. The lower part of each such pivots. The movement of the strips is in the H direction towards the sash which actuates them, and the strips thereby come into longitudinal engagement with the sashes, as shown in Fig. 2, so that the latter are held firmly against the parting strips 4 and by the strips.

Although a specific embodiment of the invention has been illustrated and described, it will be understood that various alterations in the details of construction without departing from the scope of the inventi on as indicated by the appended claims.

What I claim is 1. A window construction comprising a frame, a sash slidably mounted therein, and a sealing strip pivotally attached intermediate its ends to said frame and having a free swinging movement at both sides of the pivotal attachment, and a spring connecting one end of said strip to said frame whereby to prgject the other end into the path of said sas 2. A window construction comprising a frame, a pair of sashes slidably mounted therein, sealing strips pivotally attached intermedi ate their ends to said frame, each strip having a free swinging movement at both sides of its pivotal attachment, and springs connecting said strips to said frame whereby to project a part of each strip into the paths of said sashes.

also sealed may be made H 3. In combination with a frame and a closure member slidably mounted to cover and uncover the frame, sealing strips pivoted to said frame intermediate their ends and each having one end adapted to project into the path of said closure member in the closing movement thereof, whereby such closing movement swings the remaining ends of said strips against said closure member.

4. In combination with a frame and a closure member slidably mounted to cover and uncover the frame, sealing strips pivoted to said frame intermediate their ends and each having one end adapted to project into the path of said closure member in the closing movement thereof, whereby such closing movement swings the remaining ends of said strips against said closure member, and springs acting on said strips for positively projecting the first named ends into said path.

In testimony whereof I affix my signature.
